Mapping user journey in a single device across multiple browsers

[AnkitSi6]

I want to know how to map a user who uses multiple browsers in a single device. The person has never logged in. what to do in such a case.

do i need Customer journey analytics to map users (who are not logged in) but browse website using multiple browsers in the same device or without Customer journey analytics, I can map these users.

The problem statement is: how to identify and figure out the journey of a user who has visited my website using meta's in-app browser, then later on visited my website using google chrome. In this case, 2 ECIDs are generated. In both cases, user did not log-in. So how do i track this person's behavior. In both cases, the device used was same.

If a user uses different browsers and doesn’t log in, you can’t track them as the same person. Each browser creates a new ID. Even with Customer Journey Analytics, you need a common ID (like login or email) to link their journey.

Ok. So any reason why we cant use a device ID (GAID, IDFA) to map ECIDs?

So let's say a person, who does not log in (in both cases), using Device A from chrome browser & secondly use firefox browser (again device A, the same), why can't I map this user using Device ID & ECID?

Since the common identifier is device ID in both browsers in a single device.

In CJA, with graph based stitching, you can use multiple IDs to stitch together a single person, so it seems that should work.  There are some caveats, however.  Chief among them is it doesn't have full support for shared devices.  You can review more details in Adobe's stitching documentation - https://experienceleague.adobe.com/en/docs/analytics-platform/using/stitching/gbs

Hi

again circling back to same question. For stiching without PII (email or phone), do I need CJA (customer journey analytics) or not?

Any reason if I dont want to stich user journey without using PII (email or phone), why do i still need Customer journey analytics (CJA)?

Hi @Josh__Stephens,

Would you be able to support @AnkitSi6 further on this, or should we escalate it to our internal SMEs? Let me know what do you think.

Thanks!

As far as I'm aware, any stitching requires CJA. You can use hashed IDs for stitching.

In addition to stitching, another of CJA's key value propositions is the ability to include event datasets outside web to get a full view into the customer journey.
